[0002] Reverse osmosis, abbreviated as RO, is a membrane separation operation that separates solvents from solutions with a pressure difference as the driving force. As an efficient and energy-saving separation technology, reverse osmosis technology has been widely used in many fields. However, during the application of reverse osmosis technology, a part of wastewater will be generated, and this part of wastewater can realize the recovery and reuse of energy through energy recovery technology. The principle of energy recovery technology is to force water out of a high-concentration solution through reverse osmosis, and use the pressure difference generated during this process to realize the recovery and reuse of energy. Therefore, the energy recovery device plays a role in improving energy efficiency and reducing costs in reverse osmosis applications.

[0003] In a reverse osmosis concentrated water pressure energy recovery device disclosed in the publication number CN215901288U, although the utility model uses a long plate to push a piston plate to move, so that the air in the groove enters the airbag, and the airbag expands and extends into the card slot, which can seal the connection between the first pipe and the second pipe. There is no need to connect the pipes with tools such as bolts and nuts, avoiding the corrosion of bolts and nuts and other tools due to long-term exposure to water, and avoiding the loosening of the pipe connection; moving the vertical rod into the limit slot can fix the long plate, thereby preventing the airbag from shrinking and ensuring that the two pipes are always in a sealed state during use, preventing leakage during the transportation of water flow.

[0029] Embodiment 1

[0030] Refer to Figure 1 -4, which is the first embodiment of the present utility model, provides an efficient reverse osmosis energy recovery device. This structure includes:

[0031] An energy recovery device body 100, with fixed pipes 101 arranged on both sides of the energy recovery device body 100, facilitating the connection between the energy recovery device body 100 and the water delivery pipe 302 through the fixed pipes 101;

[0032] An installation component 200, including an installation plate 201, with installation holes opened on the installation plate 201. A fixing rod 202 is inserted into the installation holes. A limiting block 203 is fixedly connected to the top of the fixing rod 202. A first spring 204 is fixedly connected to the inner bottom wall of the limiting block 203. A control rod 205 is inserted into the first spring 204. A pressing pad 206 is fixedly connected to the top of the control rod 205. During use, pressing down the pressing pad 206 causes the control rod 205 to move downward, driving the connecting rod 2023 to rotate. At this time, the two clamping blocks 2021 move towards each other and contract into the rectangular groove. The extension piece 2022 prevents the clamping blocks 2021 from shifting during recovery, resulting in the inability of the clamping blocks 2021 to extend. Then, the fixing rod 202 is inserted into the installation hole and the pressing pad 206 is released. The first spring 204 drives the pressing pad 206 and the control rod 205 to rebound and move upward under the action of no force. At this time, the rotation of the connecting rod 2023 drives the two clamping blocks 2021 to move relatively. By the clamping blocks 2021 abutting against the holes at the installation part, the installation plate 201 and the energy recovery device body 100 can be quickly installed and disassembled;

[0033] The connecting component 300 includes a connecting pipe 301 and a water delivery pipe 302. The connecting pipe 301 is sleeved on the surface of the fixed pipe 101, and the water delivery pipe 302 is inserted into the interior of the fixed pipe 101. A clamping groove is formed on the inner wall of the connecting pipe 301, and a clamping slot is formed on the outer wall of the water delivery pipe 302. An active bead 303 is movably connected at the clamping groove and the clamping slot. One end of the connecting pipe 301 is fixedly connected with a sealing ring 304. During use, when pulling the connecting pipe 301 towards the energy recovery device body 100, the second spring 3011 is stressed and contracts. At this time, the active bead 303 is not abutted at the clamping groove, and the water delivery pipe 302 can be pulled out. When installing, similarly pull the connecting pipe 301 to make the active bead 303 not abutted, then insert the water delivery pipe 302 into the fixed pipe 101 and release the connecting pipe 301. At this time, the second spring 3011 drives the connecting pipe 301 to rebound without force, so that the clamping groove presses the active bead 303 downward into the clamping slot, and the water delivery pipe 302 and the energy recovery device body 100 can be quickly installed. Then, the sealing performance of the connecting pipe 301 is increased through the sealing ring 304 to prevent leakage.

[0034] Further, a cavity is formed inside the fixed rod 202, and a rectangular groove is formed on the inner wall of the cavity. The mechanical structure of the installation component 200 is installed through the cavity, so that the fixed rod 202 plays a protective role for the internal structure.

[0035] Further, a clamping block 2021 is slidably connected in the rectangular groove, and an extension piece 2022 is fixedly connected to one side of the clamping block 2021. Through the arrangement of the extension piece 2022, when the clamping block 2021 is retracted into the rectangular groove, it will not be displaced due to elasticity, resulting in the inability of the clamping block 2021 to extend.

[0036] Further, the other side of the clamping block 2021 is rotatably connected with a connecting rod 2023, and one end of the connecting rod 2023 is rotatably connected to the bottom of the control rod 205. The rotation of the connecting rod 2023 drives the movement of the clamping block 2021, so that the clamping block 2021 can be quickly extended.

[0037] Further, a fixing block 2051 is also sleeved on the surface of the control rod 205, and the fixing block 2051 is fixedly connected to the inner wall of the cavity. By limiting the bottom end of the first spring 204 through the fixing block 2051, after releasing the pressing pad 206, the first spring 204 can drive the pressing pad 206 to rebound.

[0038] Even further, an abutting ring is provided on the surface of the fixed pipe 101. One side of the abutting ring abuts against the inner wall of one side of the connecting pipe 301, and the other side of the abutting ring is fixedly connected with a second spring 3011. The elasticity of the second spring 3011 can drive the connecting pipe 301 to rebound, thereby pressing the active bead 303 into the clamping slot.

[0039] During use, first press down the pressing pad 206 to move the control rod 205 downward, driving the connecting rod 2023 to rotate. At this time, the two clamping blocks 2021 move towards each other and contract into the rectangular groove. The extension piece 2022 is used to prevent the clamping blocks 2021 from shifting during recovery, resulting in the inability of the clamping blocks 2021 to extend. Then insert the fixing rod 202 into the mounting hole and release the pressing pad 206. The first spring 204 drives the pressing pad 206 and the control rod 205 to rebound and move upward under the action of no force. At this time, the two clamping blocks 2021 are driven to move relative to each other through the rotation of the connecting rod 2023, and the clamping blocks 2021 are abutted against the holes at the mounting part, so that the mounting plate 201 and the energy recovery device body 100 can be quickly installed and disassembled;

[0040] Finally, pull the connecting pipe 301 towards the energy recovery device body 100, so that the second spring 3011 is stressed and contracts. At this time, the movable bead 303 is not abutted at the clamping groove, and the water delivery pipe 302 can be pulled out. When installing, also pull the connecting pipe 301 so that the movable bead 303 is not abutted, and then insert the water delivery pipe 302 into the fixed pipe 101 and release the connecting pipe 301. At this time, the second spring 3011 drives the connecting pipe 301 to rebound under the action of no force, so that the clamping groove presses the movable bead 303 downward into the clamping groove, and the water delivery pipe 302 and the energy recovery device body 100 can be quickly installed. Then, the sealing ring 304 is used to increase the sealing performance of the connecting pipe 301 to prevent leakage.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
